All Data

The responses (survival, growth, and/or reproduction) of test organisms in six concentrations of toxicants in several test waters with different water quality characteristics. In addition to the individual biological data, chemical, and water quality measurements from each toxicity test are also reported. Test organisms include unionid mussels (Lampsilis siliquoidea, Villosa iris), a...

The dataset contains GPS survey data from two surveys conducted after a flow event on February 15, 2019, at the USGS continuous slope-area (CSA) gage 09484201 - Bear Creek above Bear Canyon Road, near Tucson, AZ. The CSA gage is located downstream from Pima County Regional Flood Control District ALERT gage 2184 - Bear Canyon Wash near Bear Canyon Rd. The first survey, on February 19...

This is a fifty-four second video which includes short segments compiled from video collected using GoPro cameras mounted on two individual loggerhead turtles (Caretta caretta) within St. Joseph Bay, Florida as part of a preliminary data release for U.S. Geological Survey (USGS) outreach publications. Approximately 90 minutes of video footage was collected per individual prior to...

Monitoring of vitamin B1 (thiamine) in the eggs of lake trout (Salvelinus namaycush) collected from lakes Huron and Michigan has been conducted by the U.S. Geological Survey since the mid-1990?s. The results of this monitoring effort have been used by natural resource management agencies and native American tribes within the Great Lakes basin to evaluate the reproductive health of lake...

Measuring the thermal output of Yellowstone’s large magmatic system is not straightforward, as there are thousands of thermal features spread across 3470 square miles. One way to capture and integrate the thermal discharge from this broad area is to monitor river chemistry, because thermal water discharge eventually enters a nearby river, which acts as a collection and delivery system...

This topobathymetric digital elevation model (TBDEM) represents the topography and bathymetry for the Eastern Shore peninsula of Virginia, including Accomack and Northampton counties, and extending into Worcester and Somerset counties in Maryland. The TBDEM has a horizontal grid spacing of 1 meter and vertical units of 1 (integer) centimeter. This dataset combines U.S. Geological Survey...

Several canals in southern Florida run from Lake Okeechobee through the Everglades Agricultural Area (EAA) and feed water to the northern Everglades. Agricultural and water-management practices affect the water quality of these canals. Fertilizers added in the EAA flow into the canals and are transported to treatment areas which remove much of the phosphorous in the water, but are not as...

Airborne electromagnetic (AEM) and magnetic survey data were collected during March 2018 along 1,637 line line-kilometers over the western Hualapai Indian Reservation and surrounding areas. The survey was conducted as part of a study of the groundwater resources of the Truxton basin and Hualapai Plateau. The survey was designed to improve the understanding of the geometry of the major

Geomorphometry for Streams and Floodplains in the Chesapeake and Delaware Watersheds was generated as part of the project Quantifying Floodplain Ecological Processes and Ecosystem Services in the Delaware River Watershed funded through the William Penn Foundation's Delaware Watershed Research fund. This dataset contains geomorphometry for streams and floodplains in the Chesapeake and...

The dataset documents the spatial and temporal variability of nutrients and related water quality parameters at high spatial resolution in the North Delta, Central Delta, and the Western Delta out to Suisun Bay in the Sacramento-San Joaquin River Delta of California, USA. The dataset includes nitrate, ammonium, phosphate, dissolved organic carbon, temperature, conductivity, dissolved...

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the...
